Is it possible to create a highly-available OCFS2 cluster (i.e., A storage cluster that mitigates the single point of failure [SPoF] created by storing an OCFS2 volume on a single LUN)? The OCFS2 Project Page makes this claim... > OCFS2 is a general-purpose shared-disk cluster file system for Linux capable of providing both high performance and high availability. ...but without backing-up

Hi, I''ve created snapper packages for Ubuntu, available on https://launchpad.net/~snapper/+archive/stable. For those new to snapper, it''s a tool for managing btrfs snapshots (http://en.opensuse.org/Portal:Snapper). It depends on libblocxx available from https://launchpad.net/~bjoern-esser-n/+archive/blocxx , and currently uses git source up to commit 50dec40. I''ve done

I've been looking into using Gluster to replace a system that we currently use for storing data for several thousand users. With our current networked file system, each user can create volumes and only that user has access to their volumes with authentication. I see that Gluster also offers a username/password auth system, which is great, but there are several issues about it that bother me:

What are the recommendations for running KVM images on BTRFS systems using kernel 3.4?  I saw older posts on the web complaining about poor performance, but I know a lot of work has gone into btrfs since then.  There also seemed to be the nocow option, but I didn''t find anything that said it actualy helped. Anybody have ideas? Thanks, Matt -- To unsubscribe from this list: send the line

Hey guys, I've put up a wiki page with a kvm PCI todo list, mainly to avoid effort duplication, but also in the hope to draw attention to what I think we should try addressing in KVM: http://www.linux-kvm.org/page/PCITodo This page could cover all PCI related activity in KVM, it is very incomplete. We should probably add e.g. IOMMU related stuff. Note: if there's no developer listed for

sorry forgot to follow the protocol, now included RFC in the subject. Hi, Appears that no one is working on the auto-snapshot feature for btrfs, so here I am implementing the same. Below is a draft on the feature list. Any comments / questions / suggestions are welcome, please do let me know. btrfs auto snapshot feature will include: Initially: - configurable timely

Hello, We''re a team of 4 final year computer science students and are working on generating a diff between file system snapshots using the send receive code. The output of our utility looks like this- (I''ve tested it on a small subvol with minimal changes just to give an idea) root@nafisa-M-6319:/mnt/btrfs# btrfs sub diff -p /mnt/btrfs/snap1 /mnt/btrfs/snap2
